Problems solved by technology

Moreover, this situation may adversely affect the efficient execution of downlink packet scheduling or time-frequency-energy distribution in cellular environments
[0012] In addition, when a control signal such as an ACK / NACK signal at the transmitting end fails to be transmitted on a downlink / uplink channel, there is a reliability problem in transmitting the corresponding signal

Embodiment Construction

[0045] Reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings.

[0046] In general, the base station transmits an ACK / NACK signal, which indicates whether the data packet transmitted by each user equipment in the cell is successfully received or failed to receive; or a control signal, which acts as a link with the corresponding user equipment in the downlink. The ACK / NACK signal plays a similar role. In this way, when multiple user equipments can transmit uplink data packets in a single TTI, the base station can also transmit ACK / NACK signals to these multiple user equipments in a single TTI at the same time.

[0047] In addition, the base station multiplexes a plurality of power control signals to control the transmission power of uplink data of multiple user equipments within a single TTI in the cell, and then transmits the multiplexed signal to each user equipment.

[0048] Therefor...

Abstract

A method of transmitting a control signal using efficient multiplexing is disclosed. The present invention includes the steps of multiplexing a plurality of 1-bit control signals within a prescribed time-frequency domain by code division multiple access (CDMA) and transmitting the multiplexed control signals, wherein a plurality of the 1-bit control signals include a plurality of the 1-bit control signals for a specific transmitting side. Accordingly, reliability on 1-bit control signal transmission can be enhanced.

Description

[0001] This application is submitted on April 2, 2009, and the international application date is October 2, 2007. The application number is 200780036950.8 (PCT / KR2007 / 004825), and the title of the invention is "Using effective multiplexing to transmit control signals A divisional application of the "method" patent application. technical field [0002] The invention relates to a method for transmitting control signals in a multi-carrier mobile communication system, in particular to a method for transmitting control signals. Although the scope of application of the present invention is wide, it is particularly suitable for reliable transmission of control signals by efficiently multiplexing a plurality of 1-bit control signals in up / downlink transmission. Background technique [0003] Generally, in a multi-carrier mobile communication system, a base station performs downlink data packet transmission to a plurality of user equipments (UEs) belonging to one cell or to each of a ...
